Question about Garmin Nuvi 40

Open Question

I can't get maps on my GPS and when I do it tells me the wrong directions like my car is off the road

Every time when I turn on my GPS, I get a little message saying "cannot unlock maps" and then another one appeared saying no detailed maps were found and must be available. When I try to input the rout, a message appears and says "map data is not available". However, my favorites are still there but when I get the GPS to set a course, it tells me the wrong directions ( like my car is off the main road) Can you help me?

This is because your map file has either been deleted or corrupted and needs to be replaced. Please see this link for more info. Too much info to copy & paste here:

You need to unlock the unit. I had the same problem with one that I have. Try this:

  • The maps on the GPS device have been disabled
To determine the cause of the message, touch the screen until the message No Detailed Maps Found That Support Routing disappears.
  • If you get a Can't Unlock Maps message following this error remove any microSD / SD cards in the device and follow the instructions below for Retrieving your unlock codes followed by the instructions for Creating an unlock file.

I had the same problem. What you do is place your finger in the lower right corner where the green button would be and cut it on. When the prompt comes up, click yes. when the no detailed maps comes up again, hold down the green button again. You should then be able to upload the maps.

SOURCE: garmin nuvi says, "no detailed maps found to support routing."

I am very sorry to hear that you are having problems with the unit. You
may need to switch the unit on and press and hold the centre of the
screen until the message ?No detailed maps? message disappears.

If your map detail is missing, then the map information may have been
disabled. To check to see if the mapping has been disabled, follow the
steps below:

From the Where to? and View Map page, touch the Spanner icon, settings
(Tools).
Touch Map.
Touch Map Info.
The unit should display the name of the map that is loaded to the unit.
The box in front of the map name should have a tick in it. If it does
not, touch the box to place a tick in it.

Then please test by searching for an address.

Bought a new Garmin Nuvi 40LMgive wrong direction from day one. do i need to take it back or is there some way i can correct it?


Get your money back and spend it on a good road map. I use the latest Philips navigator UK map, it never fails and keeps my old brain functioning.

I have a friend who uses a satellite navigation system. Having met up at a place, I knew he asked me how to get to somewhere local, I said go back the way you came and at the big church, turn left - I didn't see any church he said, I was following Sat Nav - that is the point without sat nav we become aware of what is around us so we learn our way, even in strange places, by looking at the sun we can work out whether we need to go east west, etc..

Get your money back and buy a map!

Was going north and the map said i was going south


Are you sure you were heading north at that particular time?
Gps show your direction at that moment and time. Just because your road is going north does not mean that the road is always going north, sometimes they change directions to go around obstacles that were in the way of the road design, IE mountain, town, river.
The sign for the highway may say your are heading north when in actuality you are heading south to go around something.

The gps will not take into consideration the curve of the road, it just tells you the direction you are heading. Hope this helps.

Do I Need Updates?


Without access to your GPS and its make / model it is difficult to say if you have old maps or not.

Is it that it is taking you the long way around to places you know instead of using newer roads ?

It takes a long time for the GPS people to get all the latest roads into the system.

Thats why such as the TOMTOM have minor updates options the people submit so that your GPS will be aware of a closed road or some smaller new roads.

If your device supports going on-line for updates let it check for you and if it says there are newer maps or has an option to check for newer maps let it.
You are not committed to buy it but at least you will know

My Garmin cannot find the lake house. Directions


You may need to update your maps. If they are up to date (2010) then its just bad data from Navteq. You can add the waypoint in your nuvi and custom name it which would provide better results.

Map directions


TomTom has merged with Tele Atlas so that's a no go on the NAVTEQ maps. Newly built roads may not immediately show up on your TomTom, but you can definitely try upgrading your maps and using the Map Share feature to keep your maps as up to date as possible

I Would like to update my Garminc330. I have a glitch in the map (tells me address doesnot exist, when I know it does)


Garmin puts out map updates on a regular basis. You must purchase these. The GPS comes loaded with maps that are current as of the date of production of the unit. It cannot "know" when new roads are paved and new subdivision are created without being "told" via map updates. The unit knows where it is in relation to the maps loaded on it by receiving signals from the GPS satellites in orbit. If things change, the maps must be changed in order for the unit to give you correct directions.
